Hi
I wonder if there's a smarter way to do this procedure.
I have a vector of filenames wher I only am interested in the first part of
the filename.
I would use the following method of extracting the first part. But is there
a more simple way of doing this?
Names <-
c("A1-F1.txt","A2-F1.txt","AB1-F1.txt","A1-F2.txt","AB1-F2.txt","B1-F2.txt")
#..
temp <- strsplit(Names,"-")
temp <- unlist(temp)
temp <- temp[seq(from=1,to=2*length(Names),by=2)]
> temp
[1] "A1" "A2" "AB1" "A1" "AB1" "B1"
Thanks for any feedback.
Regards Tom
